Rex With Kyler Murray's status in doubt for Sunday's game, the Cardinals promoted quarterback Drew Anderson from the practice squad Saturday.
Coach Kliff Kingsbury had said Friday the move was coming "so we have every scenario covered."
To make room on the roster, the Cardinals placed tight end Darrell Daniels (biceps) on injured reserve.
Murray, who is dealing with a hamstring injury, still could be active. Kingsbury didn't rule out having all three quarterbacks active for the game. If Murray cannot play at all, Anderson will be the backup for Brett Hundley. Kingsbury also said there is a chance all three were active with Murray simply there for an emergency situation while Hundley starts. The Cardinals could also in theory test-drive Murray early in the game and if he could not continue, they would still have Hundley and Anderson available.
Anderson, an undrafted rookie from Murray State, was with the Cardinals through the offseason and preseason. He was released when the team signed Kyle Sloter to the practice squad at the outset of the regular season, and brought back to the practice squad when Sloter signed with the Detroit Lions in November.
